The Climate, Land (Food), Energy and Water systems approach (CLEWs) focuses on assessing interlinkages between resource systems in order to understand how these are related with each other, where pressure points exist, and how to minimize trade-offs while potentiating synergies. The framework is applicable to different geographical scales, from global, to regional, national and urban levels. ​The tool is used and actively developed in partnership with UNDESA and the UNDP.

Water Utilities // Smart Solution to Improve Water-Energy Nexus for Water Supply Systems

By Jorge Helmbrechta, Jordi Pastorb and Carolina Moyac. The Water-Energy Nexus is considered as one of the most important multidisciplinary challenges that the global growing water market has to face in the forthcoming years. The current trend of water transmission system to the creation of DMAs (District Metered Areas) offers great possibilities of non-structural solutions that use existing data and transform them into useful information to support decision making. This paper presents a smart...

﻿﻿ESCWA is implementing a UN Development Account (DA) Project on “Developing the Capacities of ESCWA Member Countries to Address the Water and Energy Nexus for Achieving Sustainable Developing Goals”. The DA project targets to strengthen the capacity of ESCWA member countries to achieve an integrated and sustainable management of water and energy resources to contribute to achieve the Sustainable Development Goals (SDGs).

This module was prepared as part of the United Nations Development Account project on developing the capacity of ESCWA Member Countries to address the water and energy nexus for achieving Sustainable Development Goals. It highlights the utilisation of renewable energy (RE) to strengthen the water and energy nexus by providing the power needed by water-related activities such as water distribution and wastewater treatment.

Tools // Water, Energy and Food Nexus Tool 2.0

Water, energy, and food are interconnected resource systems which face numerous challenges including a growing global population, economic crises, poverty and hunger, and climatic uncertainties. Meeting these challenges requires a paradigm shift in our conventional resource allocation model to account for the tight interconnections that exists among them. In working towards this goal, the authors have developed a resource allocation strategy assessment platform (WEF Nexus Tool 2.0) that aims to...

Nexus Tools // Nutrient-Energy-Water/NEW Nexus Toolkit

The Nutrient-Energy-Water/NEW Nexus Toolkit is aiming to help public and private-sector professionals find resources on onsite water reuse systems. Results can be filtered by audience, barrier and resource type. The Project is sponsored by the Scherman Foundation and collaborative grants from International Living Future Institute and Oregon Environmental Council.

The Berlin-based think tank adelphi has developed a modular-structured Urban Nexus training that promotes and institutionalises the Urban Nexus approach in Asia and the Pacific. The training links the Urban Nexus approach and global agreements, such as the Urban Agenda, the Paris Climate Agreement and the SDGs, and thus position the Urban Nexus in the context of an international reference system. Moreover, the training elaborates on the governance and planning processes needed to successfully...

Learning Sustainabilty trough Games // The Nexus! Challenge Board Game

The Nexus! Challenge board game lets its participants stand in the shoes of politicians and CEOs who jointly shape an economy that has to provide energy, water and food to its cities. From trade boycotts and bad harvests, to water shortages and plant viruses: the players face turbulence just like in the real world. They have to find ways to become resilient, either alone or in collaboration with others.

This module, implemented within a United Nations Development Account (DA) project on “Developing the capacities of ESCWA member countries to address the water and energy nexus for achieving Sustainable Developing Goals,” tackles water and energy issues from a technology transfer perspective. The aim is to further cooperation between Arab countries across industrial sectors to enhance resource efficiency and the use of renewable energy, for operations such as use and maintenance of water and...
